KARACHI: Here is a question that sounds simple and is not: your savings grew by 15 percent last year — did you get richer? In Pakistan, where inflation has at times run well into double digits, the honest answer depends on a second number most statements never print. If prices in general rose by 20 percent over the same year, your money buys less than it did at the start, despite the impressive growth on the statement. You earned a positive nominal return and a negative real return — richer in rupees, poorer in what rupees do. This distinction is arguably the most important idea in personal finance for a high-inflation country, because it changes the verdict on almost everything: bank deposits, government securities, gold, property and the stock market itself. This article explains nominal and real returns precisely, shows the arithmetic (including the common shortcut and when it misleads), and works through what the inflation test means for the choices Pakistani savers actually face.
Nominal is the number you see; real is the number you live
The nominal return is the raw percentage change in money terms: invest Rs 100,000, end with Rs 112,000, and the nominal return is 12 percent, before tax and costs. It is the number on every bank statement, fund report and index headline. Inflation is the rate at which the general level of prices rises, measured in Pakistan principally by the Consumer Price Index compiled by the Pakistan Bureau of Statistics — the basket, method and current readings are explained in our article on inflation in Pakistan. The real return strips inflation out, expressing your gain in purchasing power: how much more stuff — food, fuel, school fees, square feet — your money commands at the end than at the beginning.
The exact relationship is given by the Fisher equation: (1 + real return) = (1 + nominal return) ÷ (1 + inflation). Equivalently, real return = [(1 + nominal) ÷ (1 + inflation)] − 1. Work a clearly illustrative example. Suppose a deposit earns a nominal 15 percent in a year when inflation is 20 percent. The quick approximation — nominal minus inflation — gives −5 percent. The exact Fisher calculation gives (1.15 ÷ 1.20) − 1 = −4.17 percent. Either way, the verdict is the same and stark: the saver lost roughly a twentieth of their purchasing power while watching their balance grow by 15 percent. Reverse the inflation figure to 8 percent and the same 15 percent nominal return becomes a real return of about +6.5 percent exactly (approximately +7 by subtraction). The nominal number never changed; the saver's fate reversed entirely. This is why serious comparisons of investments across years, or across countries, are impossible in nominal terms alone.
Note also that the real return that matters is after tax and costs, because tax is levied on nominal gains. In a high-inflation year, a saver can owe tax on "profit" that is entirely inflation — the balance grew, the purchasing power did not, and the tax bill still arrives. Current withholding and income-tax treatments for deposits, dividends and capital gains are set by finance legislation and change over time; check the FBR's current guidance for your case. The conceptual point stands regardless of the rates in force: judge every investment as after-tax nominal return, deflated by inflation. Anything less flatters the asset and short-changes the saver.
The silent tax: what inflation does to cash and deposits
Cash under a mattress earns a nominal return of zero, so its real return is exactly negative inflation: at an illustrative 15 percent inflation, idle cash loses about 13 percent of its purchasing power in a single year (1 ÷ 1.15 − 1), and repeats the loss, compounding, every year it sits. Bank deposits soften the blow by whatever nominal rate they pay, but whenever the deposit rate runs below inflation — a condition Pakistanis have experienced for extended periods, particularly when policy rates lagged a price surge — the account balance grows while the account's command over goods shrinks. Our article on the SBP policy rate explains the mechanism that sets those deposit rates, and why they chase inflation with a delay.
The practical unit for feeling this is a familiar price. Think of what Rs 100,000 bought in school fees, atta, petrol or cement five years ago versus today; the gap between the two baskets is inflation as lived, which may differ from the official CPI if your spending leans heavily toward food, energy, education or health — categories whose prices can move faster than the average basket. Economists call this your personal inflation rate, and for planning purposes it is the more honest benchmark: a family whose budget is dominated by school fees and groceries should test its savings against the inflation it actually experiences, not only the headline statistic. The emergency fund is the one holding excused from this test — its job is availability, not growth — but excusing it does not stop the erosion, which is why even that fund is usually kept in the best-paying liquid form available rather than as literal cash.
Long horizons turn these annual leaks into floods. At a steady illustrative inflation of 10 percent, prices double in roughly seven years (the "rule of 72": divide 72 by the inflation rate to estimate doubling time). Money needed in 20 years for a child's education or your own retirement must therefore be planned in inflated terms from the start, as the goal-setting method in investing for goals demonstrates. A target written in today's rupees and reached exactly, two decades late in planning terms, is a target half missed.
Which assets have beaten inflation — and the honest caveats
The reason people accept the risks of shares, property and gold at all is the hope — supported by long-run evidence in many markets — that real assets and claims on real businesses can grow faster than prices over time. A company's revenues are themselves nominal: when inflation lifts the prices of cement, fertiliser, bank lending or consumer goods, profitable companies' earnings can rise with them, and dividends can follow, giving equities a mechanism to keep pace that a fixed-rate deposit lacks. That is the core of the case made in comparisons like property versus stocks and gold versus stocks: each asset has its own inflation behaviour, costs and failure modes. Gold's price in rupees additionally reflects the exchange rate, so its local performance often looks strongest exactly when the currency is weakest — a hedge against one specific fear, with long flat periods of its own.
The caveats are as important as the claim. Equities beat inflation over long periods, on average, across diversified holdings — not every year, not every company, and not for the investor who buys after a euphoric run and sells in the panic. In individual years, and sometimes in stretches of several years, PSX total returns (price plus dividends, as total return defines them) have fallen behind inflation, sometimes badly. High inflation is itself often hostile to share prices in the short run, because it brings high interest rates that raise companies' borrowing costs and make government securities a tempting alternative for investors' money. The inflation-beating property of equities is a long-horizon tendency earned by enduring the years when it fails, which circles back to the first rule of the subject: money that must keep its purchasing power on a fixed near date cannot rely on it.
Government securities deserve a precise mention, because they dominate Pakistani saving. Treasury bills and Pakistan Investment Bonds pay nominal rates set in the market under the shadow of the policy rate; whether those rates exceed inflation over the holding period is knowable only afterwards, though the gap between the offered rate and current inflation is the obvious first check. Inflation-linked instruments would settle the question in advance; in their absence, the saver bears the inflation risk on fixed-rate holdings — a risk that is invisible on the statement, where the nominal profit always arrives exactly as promised. Promised nominal certainty and real uncertainty are the same product described honestly.
Applying the real-return test to your own money
The test takes minutes and needs only three numbers per holding: what you put in, what it is worth plus any income received, and inflation over the same period (PBS publishes CPI changes; use the annual figure matching your horizon). Compute the nominal return, then deflate with the Fisher formula. Do it over multi-year periods, because single years mostly measure weather. Many savers who run this test for the first time discover a portfolio split in character: some holdings quietly compounding purchasing power, others — often the "safe" ones — reliably shrinking it. That discovery, not any market forecast, is the correct trigger for rebalancing a long-term plan: shifting the growth portion of savings toward assets with a plausible mechanism to outrun inflation, while keeping safety money safe and accepting its small real cost as the price of security, exactly the ordering set out in the right order for your money.
Two refinements separate careful users of the test from slogan-users. First, compare like with like on risk: a volatile asset that beat inflation by 2 percent a year and a stable one that matched it are not ranked by that fact alone; the real return is the reward, and you must still decide what reward the risk deserves. Second, beware of real-return illusions created by currency: a dollar asset's rupee return looks magnificent in a devaluation year, but if your future spending is in rupees on goods whose prices already reflect the devaluation, part of that gain is merely the measuring stick shrinking — the same caution applies in reverse when the rupee is stable. The question is always purchasing power over your future basket, in the place you will spend it.
Finally, let the concept discipline your expectations of the stock market itself. When inflation is high, nominal market returns that sound spectacular may be merely adequate in real terms — and a market that rises 25 percent in a 30-percent-inflation year has gone backwards for its owners despite the celebrations. Conversely, modest nominal gains in a low-inflation year can be genuinely good. Investors who think in real terms are harder to excite and harder to panic, because they are watching the scoreboard that actually feeds them in retirement. This article is educational content with illustrative figures, not financial advice; inflation and tax figures change, so verify current values from the Pakistan Bureau of Statistics, the SBP and the FBR when you run your own test.
One more distinction sharpens the test: expected versus experienced inflation. When you buy a fixed-rate security, the comparison that matters at purchase is its nominal rate against the inflation you expect over its life; when you judge it afterwards, the comparison is against the inflation that actually occurred. Savers are often disappointed by instruments that behaved exactly as promised, because inflation — the un-promised variable — moved against them. That disappointment carries a planning lesson: the longer the lock-in at a fixed nominal rate, the more of the outcome rests on an inflation forecast nobody can make reliably, which is one reason laddering maturities, keeping some savings in shorter instruments that reprice as rates adjust, and holding genuinely long-term money in assets with an inflation-response mechanism are recurring themes in sensible Pakistani portfolios. None of these removes inflation risk. Together, they stop a single wrong guess about prices from deciding the fate of an entire life's savings — which is, in the end, what thinking in real terms is for.
Write your own result down, holding by holding, once a year. A saver who can see, in black and white, which accounts are preserving purchasing power and which are quietly donating it to inflation has already done the hardest part of fixing the problem.
Key takeaway: subtract inflation — properly, with the Fisher formula — from every after-tax nominal return. The remainder is the only return you can actually spend.
